hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

compareTo

public int compareTo(java.lang.Object o)

Description copied from class: Constant

This method determines the relative ordering of the current constant with the constant specified, based upon the natural ordering of the constant types within the constant pool. This ordering is relevant to the maintenance of the constant pool.

Specified by:

compareTo in interface java.lang.Comparable

Overrides:

compareTo in class Constant

Parameters:

o - A Constant object with which to compare this Constant for purposes of sorting.

Returns:

A negative value if this constant is considered less than the specified constant, 0 if they are considered to have the same sort order, or a positive value if this constant is considered greater than the specified constant.

writeContent

protected void writeContent(java.io.DataOutput out)
                     throws java.io.IOException

Description copied from class: Constant

This method must be implemented by a subclass to provide the appropriate behavior when writing the binary representation of this constant to an output stream.

Specified by:

writeContent in class Constant

Parameters:

out - Output stream to which to write the portion of the binary representation of this constant which is specific to the subclass.

Throws:

java.io.IOException - if any error writing to stream.
