Method Detail

parse

public static PofValue parse(ReadBuffer buf,
                             PofContext ctx)

Parses POF-encoded binary and returns an instance of a PofValue wrapper for it.

Parameters:

buf - POF-encoded binary value

ctx - POF context to use

Returns:

a PofValue instance

parseValue

protected static PofValue parseValue(PofValue valueParent,
                                     ReadBuffer bufValue,
                                     PofContext ctx,
                                     int of)

Parse a POF-encoded binary and return an instance of a PofValue wrapping the binary.

Parameters:

valueParent - parent POF value

bufValue - buffer with POF-encoded binary value

ctx - POF context to use

of - offset of the parsed value from the beginning of the POF stream

Returns:

a PofValue instance

parseUniformValue

protected static PofValue parseUniformValue(PofValue valueParent,
                                            int nType,
                                            ReadBuffer bufValue,
                                            PofContext ctx,
                                            int of)

Parses a uniform POF-encoded binary and returns an instance of a PofValue wrapping the binary.

Parameters:

valueParent - parent POF value

nType - type identifier of this POF value

bufValue - POF-encoded binary value without the type identifier

ctx - POF context to use

of - offset of the parsed value from the beginning of the POF stream

Returns:

a PofValue instance

instantiatePofValue

protected static PofValue instantiatePofValue(PofValue valueParent,
                                              int nType,
                                              ReadBuffer bufValue,
                                              PofContext ctx,
                                              int of,
                                              ReadBuffer.BufferInput in)

Creates a PofValue instance.

Parameters:

valueParent - parent POF value

nType - type identifier of this POF value

bufValue - POF-encoded binary value without the type identifier

ctx - POF context to use

of - offset of the parsed value from the beginning of the POF stream

in - buffer input to read the value from

Returns:

a PofValue instance
