Constructor Detail

ComplexPofValue

public ComplexPofValue(PofValue valueParent,
                       ReadBuffer bufValue,
                       PofContext ctx,
                       int of,
                       int nType,
                       int ofChildren)

Construct a PofValue instance wrapping the supplied buffer.

Parameters:

valueParent - parent value within the POF stream

bufValue - buffer containing POF representation of this value

ctx - POF context to use when reading or writing properties

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

nType - POF type identifier for this value

ofChildren - offset of the first child element within this value

Method Detail

getChild

public PofValue getChild(int nIndex)

Locate a child PofValue contained within this PofValue.

Note: the returned PofValue could represent a non-existent (null) value.

Parameters:

nIndex - index of the child value

Returns:

the child PofValue

getChildrenIterator

public Iterator getChildrenIterator()

Return an iterator over all parsed child values.

Returns:

a children iterator

getUniformElementType

protected int getUniformElementType()

Return the uniform element type (if this is a uniform collection).

Returns:

uniform element type, or PofConstants.T_UNKNOWN if this is not a uniform collection

setUniformElementType

protected void setUniformElementType(int nElementType)

Set the uniform element type for this collection.

Parameters:

nElementType - uniform element type

findChild

protected PofValue findChild(int nIndex)

Find the child value with the specified index.

Parameters:

nIndex - index of the child value to find

Returns:

the child value

getLastChildIndex

protected int getLastChildIndex(int nIndex)

Return index of the last parsed child with an index lower than the specified one.

Parameters:

nIndex - index to find the preceding child index for

Returns:

index of the last parsed child, or -1 if one does not exist

isUniformCollection

protected boolean isUniformCollection()

Return true if this complex value is encoded as one of uniform collection types.

Returns:

true if this is a uniform collection

skipChild

protected void skipChild(ReadBuffer.BufferInput in)
                  throws IOException

Skip a single child value.

Parameters:

in - buffer input containing child values

Throws:

IOException - if an I/O error occurs

extractChild

protected PofValue extractChild(ReadBuffer buf,
                                int of,
                                int cb)

Extract child PofValue from a buffer.

Parameters:

buf - parent buffer to extract the child from

of - offset of the child within the parent buffer

cb - length of the child in bytes

Returns:

extracted PofValue

findChildInternal

protected abstract PofValue findChildInternal(int nIndex,
                                              int ofStart,
                                              int iStart)

Find the child value with the specified index.

Parameters:

nIndex - index of the child value to find

ofStart - offset within the parent buffer to start search from

iStart - index of the child value to start search from

Returns:

the child value
