ReverbType

protected ReverbType(String name,
                     int earlyDelay,
                     float earlyInten,
                     int lateDelay,
                     float lateInten,
                     int decay)
Create a new ReverbType given its attributes.
Parameters:
name - the name of this type
earlyDelay - the early delay time in microseconds
earlyInten - the early intensity in decibels
lateDelay - the late delay time in microseconds
lateInten - the late intensity in decibels
decay - the decay time in microseconds

Method Details

equals

public final boolean equals(Object o)
Determine whether this Object is semantically equal to another Object.

There are some fairly strict requirements on this method which subclasses must follow:

  • It must be transitive. If a.equals(b) and b.equals(c), then a.equals(c) must be true as well.
  • It must be symmetric. a.equals(b) and b.equals(a) must have the same value.
  • It must be reflexive. a.equals(a) must always be true.
  • It must be consistent. Whichever value a.equals(b) returns on the first invocation must be the value returned on all later invocations.
  • a.equals(null) must be false.
  • It must be consistent with hashCode(). That is, a.equals(b) must imply a.hashCode() == b.hashCode(). The reverse is not true; two objects that are not equal may have the same hashcode, but that has the potential to harm hashing performance.

This is typically overridden to throw a ClassCastException if the argument is not comparable to the class performing the comparison, but that is not a requirement. It is legal for a.equals(b) to be true even though a.getClass() != b.getClass(). Also, it is typical to never cause a NullPointerException.

In general, the Collections API (java.util) use the equals method rather than the == operator to compare objects. However, IdentityHashMap is an exception to this rule, for its own good reasons.

The default implementation returns this == o.

Overrides:
equals in interface Object
Parameters:
Returns:
whether this Object is semantically equal to another

getDecayTime

public final int getDecayTime()
Return the decay time.

getEarlyReflectionDelay

public final int getEarlyReflectionDelay()
Return the early reflection delay.

getEarlyReflectionIntensity

public final float getEarlyReflectionIntensity()
Return the early reflection intensity.

getLateReflectionDelay

public final int getLateReflectionDelay()
Return the late reflection delay.

getLateReflectionIntensity

public final float getLateReflectionIntensity()
Return the late reflection intensity.

getName

public String getName()
Return the name of this ReverbType.
Since:
1.5

hashCode

public final int hashCode()
Get a value that represents this Object, as uniquely as possible within the confines of an int.

There are some requirements on this method which subclasses must follow:

  • Semantic equality implies identical hashcodes. In other words, if a.equals(b) is true, then a.hashCode() == b.hashCode() must be as well. However, the reverse is not necessarily true, and two objects may have the same hashcode without being equal.
  • It must be consistent. Whichever value o.hashCode() returns on the first invocation must be the value returned on all later invocations as long as the object exists. Notice, however, that the result of hashCode may change between separate executions of a Virtual Machine, because it is not invoked on the same object.

Notice that since hashCode is used in Hashtable and other hashing classes, a poor implementation will degrade the performance of hashing (so don't blindly implement it as returning a constant!). Also, if calculating the hash is time-consuming, a class may consider caching the results.

The default implementation returns System.identityHashCode(this)

Overrides:
hashCode in interface Object
Returns:
the hash code for this Object

toString

public final String toString()
Return a description of this ReverbType.
Overrides:
toString in interface Object
