public ConstantUtf8Info()

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 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 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

getBytes

public byte[] getBytes()

Get the byte array of the string in this entry.

Returns:

the array

getString

public String getString()

Get the string in this entry.

Returns:

the string

setBytes

public void setBytes(byte[] bytes)

Deprecated. use setString instead

Set the byte array of the string in this entry.

Parameters:

bytes - the array

setString

public void setString(String string)

Set the string in this entry.

Parameters:

string - the 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

debug

protected void debug(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

equals

public boolean equals(Object object)

Overrides:

equals in class CPInfo

hashCode

public int hashCode()

Overrides:

hashCode in class CPInfo
