bytes

protected int bytes

bytes field.

Constructor Detail

ConstantNumeric

public ConstantNumeric()

Method Detail

getBytes

public int getBytes()

Get the bytes field of this constant pool entry.

Returns:

the bytes field

setBytes

public void setBytes(int bytes)

Set the bytes field of this constant pool entry.

Parameters:

bytes - the bytes field

getFormattedBytes

public String getFormattedBytes()

Get the the bytes field of this constant pool entry as a hex string.

Returns:

the hex string

read

public void read(DataInput in)
          throws InvalidByteCodeException,
                 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:

IOException - if an exception occurs with the DataInput

InvalidByteCodeException - if the byte code is invalid

write

public void write(DataOutput out)
           throws InvalidByteCodeException,
                  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

IOException - if an exception occurs with the DataOutput

equals

public boolean equals(Object object)

Overrides:

equals in class CPInfo

hashCode

public int hashCode()

Overrides:

hashCode in class CPInfo
