com.tangosol.io.pof.ValidatingPofHandler.Complex

Direct Known Subclasses:

ValidatingPofHandler.ComplexMap

Enclosing class:

ValidatingPofHandler

public class ValidatingPofHandler.Complex

extends Base

A Complex object represents the current complex data structure in the POF stream.

Constructor Summary

ValidatingPofHandler.Complex(ValidatingPofHandler.Complex complexCurrent, int cElements, boolean fContiguous)
Construct a Complex object for a data collection or user type.

ValidatingPofHandler.Complex(ValidatingPofHandler.Complex complexCurrent, int cElements, boolean fContiguous, int nUniformTypeId)
Construct a Complex object for a uniformly-typed data collection.

Method Summary

void	checkPosition(int iPos) Notify the Complex object that a value has been encountered.
int	getElementCount() Obtain the total element count.
int	getLastPosition() Obtain the last known position, which is the index (or property number) of the most recent value.
int	getNextPosition() For complex values with contiguous values, obtain the next position.
int	getUniformType() If the object encoding is using uniform encoding, obtain the type id of the uniform type.
boolean	isContiguous() Determine if the elements are contiguous.
boolean	isUniform() Determine if the object encoding within the Complex type is uniform.
ValidatingPofHandler.Complex	pop() Pop this Complex object off the stack, returning the outer Complex object or null if there is none.

Constructor Detail

ValidatingPofHandler.Complex

public ValidatingPofHandler.Complex(ValidatingPofHandler.Complex complexCurrent,
                                    int cElements,
                                    boolean fContiguous)

Construct a Complex object for a data collection or user type.

Parameters:

complexCurrent - the current Complex object or null

cElements - the total (or maximum) number of elements

fContiguous - true if the elements are contiguous

ValidatingPofHandler.Complex

public ValidatingPofHandler.Complex(ValidatingPofHandler.Complex complexCurrent,
                                    int cElements,
                                    boolean fContiguous,
                                    int nUniformTypeId)

Construct a Complex object for a uniformly-typed data collection.

Parameters:

complexCurrent - the current Complex object or null

cElements - the total (or maximum) number of elements

fContiguous - true if the elements are contiguous

nUniformTypeId - the type identifier of the uniform type

Method Detail

checkPosition

public void checkPosition(int iPos)

Notify the Complex object that a value has been encountered.

Parameters:

iPos - the position that accomponied the value

getLastPosition

public int getLastPosition()

Obtain the last known position, which is the index (or property number) of the most recent value.

Returns:

the previous position that was reported to checkPosition()

getNextPosition

public int getNextPosition()

For complex values with contiguous values, obtain the next position.

Returns:

the next position

getElementCount

public int getElementCount()

Obtain the total element count. The element count is not known (i.e. it is not limited) for user types. For sparse types, the element count is the maximum number of values in the sparse value, which is often greater than the actual number of values. For Map types, the number of values is two times the element count (since each element has a key and a value).

Returns:

the maximum element count

isContiguous

public boolean isContiguous()

Determine if the elements are contiguous.

Returns:

true for all complex types except user and sparse types

isUniform

public boolean isUniform()

Determine if the object encoding within the Complex type is uniform.

Returns:

true iff values within the Complex type are of a uniform type and are encoded uniformly

getUniformType

public int getUniformType()

If the object encoding is using uniform encoding, obtain the type id of the uniform type.

Returns:

the type id used for the uniform encoding

pop

public ValidatingPofHandler.Complex pop()

Pop this Complex object off the stack, returning the outer Complex object or null if there is none.

Returns:

the outer Complex object or null if there is none
