Constructor Detail

AnglePolicy

public AnglePolicy()

Unique public constructor.

Constructs a full-range policy displaying -180 to +180 degrees.

Method Detail

canCycle

public final boolean canCycle()

Re-implementation to return true.

Overrides:

canCycle in class NumberPolicy

format

public final int format()

Description copied from class: NumberPolicy

Hint on formatting the number.

These are defined by the class FORMAT_x constants, which are mutually exclusive.

For FORMAT_PLACES_x constants the format should normally be consistent with unit.

Overrides:

format in class NumberPolicy

incrementTitles

public java.lang.String[] incrementTitles()

Description copied from class: NumberPolicy

Human-readable description of increment directions.

Overrides:

incrementTitles in class NumberPolicy

labelSpacing

public int labelSpacing()

Description copied from class: NumberPolicy.Ticked

The number of ticks between each label.

Overrides:

labelSpacing in class NumberPolicy.Ticked

localTicks

public NumberPolicy.Ticked localTicks()

Returns a local adjustment policy with a 60º range and its snap type coupled to that of its parent.

Overrides:

localTicks in class NumberPolicy.Ticked

NumberPolicy.Ticked.labelSpacing()

snapType

public int snapType()

Description copied from class: NumberPolicy.Ticked

Defines the snap-to-ticks contentStyle.

The value returned should be one of

• SNAP_NONE
• SNAP_TICKS
• SNAP_LABELS

Overrides:

snapType in class NumberPolicy.Ticked

tickSpacing

public int tickSpacing()

Description copied from class: NumberPolicy.Ticked

The spacing between each tick, in the value returned by NumberPolicy.unit().

Overrides:

tickSpacing in class NumberPolicy.Ticked

reverseIncrements

protected final boolean reverseIncrements()

Description copied from class: NumberPolicy

Reverses the normal increment direction.

Used by validIncrement, default is false.

Overrides:

reverseIncrements in class NumberPolicy
