Interface HighlightPredicate

All Known Implementing Classes:

HighlightPredicate.AndHighlightPredicate, HighlightPredicate.ColumnHighlightPredicate, HighlightPredicate.DepthHighlightPredicate, HighlightPredicate.EqualsHighlightPredicate, HighlightPredicate.IdentifierHighlightPredicate, HighlightPredicate.NotHighlightPredicate, HighlightPredicate.OrHighlightPredicate, HighlightPredicate.RowGroupHighlightPredicate, HighlightPredicate.TypeHighlightPredicate, PatternPredicate, SearchPredicate

public interface HighlightPredicate

A controller which decides whether or not a visual decoration should be applied to the given Component in the given ComponentAdapter state. This is a on/off decision only, the actual decoration is left to the AbstractHighlighter which typically respects this predicate.

Note: implementations should be immutable because Highlighters guarantee to notify listeners on any state change which might effect the highlight. They can't comply to that contract if predicate internal state changes under their feet. If dynamic predicate state is required, the safe alternative is to create and set a new predicate.

Method Summary

boolean

isHighlighted(java.awt.Component renderer, ComponentAdapter adapter) Returns a boolean to indicate whether the component should be highlighted.

Field Detail

ALWAYS

static final HighlightPredicate ALWAYS

Unconditional true.

NEVER

static final HighlightPredicate NEVER

Unconditional false.

ROLLOVER_ROW

static final HighlightPredicate ROLLOVER_ROW

Rollover Row.

EDITABLE

static final HighlightPredicate EDITABLE

Is editable.

READ_ONLY

static final HighlightPredicate READ_ONLY

Convenience for read-only (same as !editable).

IS_LEAF

static final HighlightPredicate IS_LEAF

Leaf predicate.

IS_FOLDER

static final HighlightPredicate IS_FOLDER

Folder predicate - convenience: same as !IS_LEAF.

HAS_FOCUS

static final HighlightPredicate HAS_FOCUS

Focus predicate.

EVEN

static final HighlightPredicate EVEN

Even rows. PENDING: this is zero based (that is "really" even 0, 2, 4 ..), differing from the old AlternateRowHighlighter.

ODD

static final HighlightPredicate ODD

Odd rows. PENDING: this is zero based (that is 1, 3, 4 ..), differs from the old implementation which was one based?

BIG_DECIMAL_NEGATIVE

static final HighlightPredicate BIG_DECIMAL_NEGATIVE

Negative BigDecimals.

INTEGER_NEGATIVE

static final HighlightPredicate INTEGER_NEGATIVE

Negative Number.

EMPTY_PREDICATE_ARRAY

static final HighlightPredicate[] EMPTY_PREDICATE_ARRAY

EMPTY_OBJECT_ARRAY

static final java.lang.Object[] EMPTY_OBJECT_ARRAY

EMPTY_INTEGER_ARRAY

static final java.lang.Integer[] EMPTY_INTEGER_ARRAY

Method Detail

isHighlighted

boolean isHighlighted(java.awt.Component renderer,
                      ComponentAdapter adapter)

Returns a boolean to indicate whether the component should be highlighted.

Note: both parameters should be considered strictly read-only!

Parameters:

renderer - the cell renderer component that is to be decorated, must not be null

adapter - the ComponentAdapter for this decorate operation, most not be null

Returns:

a boolean to indicate whether the component should be highlighted.
