Method Details

unpackStructHeader

public long unpackStructHeader()
                        throws IOException

Throws:

IOException

unpackStructSignature

public byte unpackStructSignature()
                           throws IOException

Throws:

IOException

unpackListHeader

public long unpackListHeader()
                      throws IOException

Throws:

IOException

unpackMapHeader

public long unpackMapHeader()
                     throws IOException

Throws:

IOException

unpackLong

public long unpackLong()
                throws IOException

Throws:

IOException

unpackDouble

public double unpackDouble()
                    throws IOException

Throws:

IOException

unpackBytes

public byte[] unpackBytes()
                   throws IOException

Throws:

IOException

unpackString

public String unpackString()
                    throws IOException

Throws:

IOException

unpackNull

public Object unpackNull()
                  throws IOException

This may seem confusing. This method exists to move forward the internal pointer when encountering a null value. The idiomatic usage would be someone using peekNextType() to detect a null type, and then this method to "skip past it".

Returns:

null

Throws:

IOException - if the unpacked value was not null

unpackBoolean

public boolean unpackBoolean()
                      throws IOException

Throws:

IOException

peekNextType

public PackType peekNextType()
                      throws IOException

Throws:

IOException
