Method Detail

getTag

public byte getTag()

Description copied from class: CPInfo

Get the value of the tag field of the cp_info structure.

Specified by:

getTag in class CPInfo

Returns:

the tag

getTagVerbose

public java.lang.String getTagVerbose()

Description copied from class: CPInfo

Get the verbose description of the tag field of the cp_info structure.

Specified by:

getTagVerbose in class CPInfo

Returns:

the verbose description

getVerbose

public java.lang.String getVerbose()
                            throws InvalidByteCodeException

Description copied from class: CPInfo

Get the verbose description of the content of the constant pool entry.

Overrides:

getVerbose in class CPInfo

Returns:

the verbose description

Throws:

InvalidByteCodeException - if the byte code is invalid

getReferenceIndex

public int getReferenceIndex()

Get the index of the constant pool entry containing the reference.

Returns:

the index

setReferenceIndex

public void setReferenceIndex(int referenceIndex)

Set the index of the constant pool entry containing the reference.

Parameters:

referenceIndex - the index

getType

public int getType()

setType

public void setType(int type)

getName

public java.lang.String getName()
                         throws InvalidByteCodeException

Get the descriptor.

Returns:

the descriptor

Throws:

InvalidByteCodeException - if the byte code is invalid

read

public void read(java.io.DataInput in)
          throws InvalidByteCodeException,
                 java.io.IOException

Description copied from class: AbstractStructure

Read this structure from the given DataInput.

Excpects DataInput to be in JVM class file format and just before a structure of this kind. No look ahead parsing since the class file format is deterministic.

Overrides:

read in class AbstractStructure

Parameters:

in - the DataInput from which to read

Throws:

InvalidByteCodeException - if the byte code is invalid

java.io.IOException - if an exception occurs with the DataInput

write

public void write(java.io.DataOutput out)
           throws InvalidByteCodeException,
                  java.io.IOException

Description copied from class: AbstractStructure

Write this structure to the given DataOutput.

The written bytes are in JVM class file format.

Overrides:

write in class AbstractStructure

Parameters:

out - the DataOutput to which to write

Throws:

InvalidByteCodeException - if the structure is internally inconsistent

java.io.IOException - if an exception occurs with the DataOutput

equals

public boolean equals(java.lang.Object object)

Overrides:

equals in class CPInfo

hashCode

public int hashCode()

Overrides:

hashCode in class CPInfo

debug

protected void debug(java.lang.String message)

Description copied from class: AbstractStructure

Utility method for derived structures. Dump a specific debug message.

Overrides:

debug in class AbstractStructure

Parameters:

message - the debug message
