Method Detail

isSlice

default boolean isSlice()

isEQ

default boolean isEQ()

isLIKE

default boolean isLIKE()

isIN

default boolean isIN()

isContains

default boolean isContains()

isEqualityBased

default boolean isEqualityBased()

Returns:

true if this restriction is based on equality comparison rather than a range or negation

isNotNull

default boolean isNotNull()

isMultiColumn

default boolean isMultiColumn()

hasBound

default boolean hasBound(Bound b)

Checks if the specified bound is set or not.

Parameters:

b - the bound type

Returns:

true if the specified bound is set, false otherwise

isInclusive

default boolean isInclusive(Bound b)

Checks if the specified bound is inclusive or not.

Parameters:

b - the bound type

Returns:

true if the specified bound is inclusive, false otherwise

mergeWith

SingleRestriction mergeWith(SingleRestriction otherRestriction)

Merges this restriction with the specified one.

Restriction are immutable. Therefore merging two restrictions result in a new one. The reason behind this choice is that it allow a great flexibility in the way the merging can done while preventing any side effect.

Parameters:

otherRestriction - the restriction to merge into this one

Returns:

the restriction resulting of the merge

appendTo

MultiCBuilder appendTo(MultiCBuilder builder,
                       QueryOptions options)

Appends the values of this SingleRestriction to the specified builder.

Parameters:

builder - the MultiCBuilder to append to.

options - the query options

Returns:

the MultiCBuilder

appendBoundTo

default MultiCBuilder appendBoundTo(MultiCBuilder builder,
                                    Bound bound,
                                    QueryOptions options)

Appends the values of the SingleRestriction for the specified bound to the specified builder.

Parameters:

builder - the MultiCBuilder to append to.

bound - the bound

options - the query options

Returns:

the MultiCBuilder
