struct | ce_parser_arg |
class | ChildLocker |
class | chunked_inbuf |
class | chunked_istream |
class | chunked_ostream |
A C++ stream class for chunked data. This class uses the chunked_outbuf class to provide for chunked binary serialization of data as specified by DAP4. Information to be serialized is broken into 'chunks' that are no more than 2^24 bytes in length. Each chunk is prefixed by a 4 byte header that indicates the type of chunk and size (number of bytes in the chunk body). There are three types of chunk: Data; End; and Error. In normal operation, a DAP4 data document/response is serialized as a sequence of DATA chunks followed by one END chunk (which may be zero bytes in length). If, during serialization, an error is detected, the currently buffered (but not sent) data are discarded and an ERROR chunk is sent with an error message. More... | |
class | chunked_outbuf |
output buffer for a chunked stream This performs buffered output encoding the data in the stream using the simple chunking protocol defined for DAP4's binary data transmission. Each block of data is prefixed by four bytes: A CHUNK TYPE byte followed by three bytes that are the CHUNK SIZE. There are three CHUNK TYPES: data, end and error, indicated by the code values 0x00, 0x01 and 0x02. The size of a chunk is limited to 2^24 data bytes + 4 bytes for the chunk header. More... | |

MIME Utilities | |||||||
A collection of useful functions for writing MIME headers for OPeNDAP servers. The CGI utilities include a variety of functions useful to programmers developing OPeNDAP CGI filter programs. However, before jumping in and using these, look at the class ResponseBuilder. Always choose to use that class over these functions if you can. Many of these functions were used by the CGI programs that made up the first DAP server; all of those are deprecated and the ResponseBuilder class should be used instead. Some of the other functions are used by ResponseBuilder and the client-side parsing code that needs to identify MIME headers, boundaries, etc.

Integer to string conversion functions | |||||||
Fast, safe conversions from long to a character representation which gets appended to a string. This method will take a long value 'val' and it will recursively divide it by 'base' in order to "extract" one by one the digits which compose it; these digits will be appended to the string

bool | pathname_ok (const string &path, bool strict) | ||||||
Does the string name a potentially valid pathname? Test the given pathname to verify that it is a valid name. We define this as: Contains only printable characters; and Is less then 256 characters. If strict is true, test that the pathname consists of only letters, digits, and underscore, dash and dot characters instead of the more general case where a pathname can be composed of any printable characters.

Disconnected Operation
The cache can be set to handle disconnected operation where it does not use the network to validate entries and does not attempt to load new documents. All requests that cannot be fulfilled by the cache will be returned with a "504 Gateway Timeout" response. There are two operational disconnected modes:
No network activity at all: Here it uses its own persistent cache to answer the request, if possible.
Forward all disconnected requests to a proxy cache: Here it uses the HTTP/1.1 cache-control header to indicate that the proxy should operate in disconnected mode.

enum libdap::EncodingType |
The type of encoding used on the current stream.
libdap understands two types of encoding: x-plain and deflate, which correspond to plain uncompressed data and data compressed with zlib's LZW algorithm respectively.

Definition at line 48 of file EncodingType.h.
enum libdap::ObjectType |
The type of object in the stream coming from the data server.
When a version 2.x or greater DAP data server sends an object, it may use the Content-Description header of the response to indicate the type of object contained in the response.

Open a temporary file and return its name. This method opens a temporary file using get_tempfile_template(). The FILE* stream
is opened for both reads and writes; if it already exists (highly unlikely), it is truncated. If used on Unix, it's the callers responsibility to unlink the named file so that when all descriptors to it are closed, it will be deleted. On Win32 platforms, this method pushes the name of the temporary file onto a vector which is used during object destruction to delete all the temporary files.

Consume the Multipart MIME headers that prefix the DDX in a DataDDX response. The stream pointer is advanced to the start of the DDX. It might seem odd that this function both takes the value of the MPM boundary as a parameter and returns that value as a result, but this code can be used in two different situations. In one case, it is called on a partial document read from stdin and needs to return the value of boundary to the downstream DDX parser so that code can sense the end of the DDX. In the other case, this function is told the value of boundary and tests for it to ensure document correctness.

void libdap::set_array_using_double | ( | Array * | dest, |
double * | src, | ||
int | src_len | ||
) |
Given an array that holds some sort of numeric data, load it with values using an array of doubles. This function makes several assumptions. First, it assumes the caller really wants to put the doubles into whatever types the array holds! Caveat emptor. Second, it assumes that if the size of source (src) array is different than the destination (dest) the caller has made a mistake. In that case it will throw an Error object.
After setting the values, this method sets the read_p
property for dest. Setting read_p tells the serialization methods in libdap that this variable already holds data values and, given that, the serialization code will not try to read the values.
dest | An Array. The values are written to this array, reusing its storage. Existing values are lost. |

void libdap::set_mime_not_modified | ( | FILE * | out | ) |
Send a ‘Not Modified’ response.
Use this function to create a response signaling that the target of a conditional get has not been modified relative to the condition given in the request. This will have to be a date until the servers support ETags.
out | Write the response to this FILE pointer. |

Generate an HTTP 1.0 response header for a text document. This is used when returning a serialized DAS or DDS object.

type | The type of this this response. Defaults to application/octet-stream. |

Return the type name. This function provides backward compatibility for older code that predates, and has not been ported to, DAP4. It is prejudiced toward DAP4, but if no D4 type name can be found, it types D2. If neither would return a type name, and InternalErr object is thrown.

string libdap::unescattr | ( | string | s | ) |
Un-escape special characters, quotes and backslashes from an HDF attribute.
Note: A regex to match one \ must be defined as: Regex foo = "\\\\"; because both C++ strings and GNU's Regex also employ \ as an escape character!
s | The escaped attribute. |

Given a string that contains WWW escape sequences, translate those escape sequences back into the ASCII characters they represent. Return the modified string.
-Places in the dap code where www2id() is called:
-In the server code:
in | The string to modify. |
escape | The character used to signal the beginning of an escape sequence. default: "%" |
except | If there are some escape codes that should not be removed by this call (e.g., you might not want to remove spaces, %20) use this parameter to specify those codes. The function will then transform all escapes except those given. For example, to suppress translation of both spaces and the ampersand, pass "%20%26" for 'except'. default: "" |

string libdap::xml2id | ( | string | in | ) |
Given a string that contains XML escape sequences (i.e., entities), translate those back into ASCII characters. Return the modified string.
