public final Class FontLineMetrics

Overrides java.lang.Object.clone.

Doc from java.lang.Object.clone.

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

x.clone() != x

x.clone().getClass() == x.getClass()

x.clone().equals(x)

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Implements abstract java.awt.font.LineMetrics.getAscent.

Doc from java.awt.font.LineMetrics.getAscent.

Returns the ascent of the text. The ascent is the distance from the baseline to the ascender line. The ascent usually represents the the height of the capital letters of the text. Some characters can extend above the ascender line.

Implements abstract java.awt.font.LineMetrics.getBaselineIndex.

Doc from java.awt.font.LineMetrics.getBaselineIndex.

Returns the baseline index of the text. The index is one of ROMAN_BASELINE, CENTER_BASELINE, HANGING_BASELINE.

Implements abstract java.awt.font.LineMetrics.getBaselineOffsets.

Doc from java.awt.font.LineMetrics.getBaselineOffsets.

Returns the baseline offsets of the text, relative to the baseline of the text. The offsets are indexed by baseline index. For example, if the baseline index is CENTER_BASELINE then offsets[HANGING_BASELINE] is usually negative, offsets[CENTER_BASELINE] is zero, and offsets[ROMAN_BASELINE] is usually positive.

Implements abstract java.awt.font.LineMetrics.getDescent.

Doc from java.awt.font.LineMetrics.getDescent.

Returns the descent of the text. The descent is the distance from the baseline to the descender line. The descent usually represents the distance to the bottom of lower case letters like 'p'. Some characters can extend below the descender line.

Implements abstract java.awt.font.LineMetrics.getHeight.

Doc from java.awt.font.LineMetrics.getHeight.

Returns the height of the text. The height is equal to the sum of the ascent, the descent and the leading.

Implements abstract java.awt.font.LineMetrics.getLeading.

Doc from java.awt.font.LineMetrics.getLeading.

Returns the leading of the text. The leading is the recommended distance from the bottom of the descender line to the top of the next line.

Implements abstract java.awt.font.LineMetrics.getNumChars.

Doc from java.awt.font.LineMetrics.getNumChars.

Returns the number of characters (char values) in the text whose metrics are encapsulated by this LineMetrics object.

Implements abstract java.awt.font.LineMetrics.getStrikethroughOffset.

Doc from java.awt.font.LineMetrics.getStrikethroughOffset.

Returns the position of the strike-through line relative to the baseline.

Implements abstract java.awt.font.LineMetrics.getStrikethroughThickness.

Doc from java.awt.font.LineMetrics.getStrikethroughThickness.

Returns the thickness of the strike-through line.

Implements abstract java.awt.font.LineMetrics.getUnderlineOffset.

Doc from java.awt.font.LineMetrics.getUnderlineOffset.

Returns the position of the underline relative to the baseline.

Implements abstract java.awt.font.LineMetrics.getUnderlineThickness.

Doc from java.awt.font.LineMetrics.getUnderlineThickness.

Returns the thickness of the underline.

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
