Method Detail

addElementToAll

public CompositesBuilder addElementToAll(java.nio.ByteBuffer value)

Adds the specified element to all the composites.

If this builder contains 2 composites: A-B and A-C a call to this method to add D will result in the composites: A-B-D and A-C-D.

Parameters:

value - the value of the next element

Returns:

this CompositeBuilder

addEachElementToAll

public CompositesBuilder addEachElementToAll(java.util.List<java.nio.ByteBuffer> values)

Adds individually each of the specified elements to the end of all of the existing composites.

If this builder contains 2 composites: A-B and A-C a call to this method to add D and E will result in the 4 composites: A-B-D, A-B-E, A-C-D and A-C-E.

Parameters:

values - the elements to add

Returns:

this CompositeBuilder

addAllElementsToAll

public CompositesBuilder addAllElementsToAll(java.util.List<java.util.List<java.nio.ByteBuffer>> values)

Adds individually each of the specified list of elements to the end of all of the existing composites.

If this builder contains 2 composites: A-B and A-C a call to this method to add [[D, E], [F, G]] will result in the 4 composites: A-B-D-E, A-B-F-G, A-C-D-E and A-C-F-G.

Parameters:

values - the elements to add

Returns:

this CompositeBuilder

remainingCount

public int remainingCount()

Returns the number of elements that can be added to the composites.

Returns:

the number of elements that can be added to the composites.

hasRemaining

public boolean hasRemaining()

Checks if some elements can still be added to the composites.

Returns:

true if it is possible to add more elements to the composites, false otherwise.

isEmpty

public boolean isEmpty()

Checks if this builder is empty.

Returns:

true if this builder is empty, false otherwise.

containsNull

public boolean containsNull()

Checks if the composites contains null elements.

Returns:

true if the composites contains null elements, false otherwise.

hasMissingElements

public boolean hasMissingElements()

Checks if some empty list of values have been added

Returns:

true if the composites have some missing elements, false otherwise.

containsUnset

public boolean containsUnset()

Checks if the composites contains unset elements.

Returns:

true if the composites contains unset elements, false otherwise.

build

public java.util.List<Composite> build()

Builds the Composites.

Returns:

the composites

buildWithEOC

public java.util.List<Composite> buildWithEOC(Composite.EOC eoc)

Builds the Composites with the specified EOC.

Returns:

the composites
