Method Detail

convert

public E convert(ParsedValue<String,E> value,
                 Font not_used)

Description copied from class: StyleConverter

Convert from the parsed CSS value to the target property type.

Overrides:

convert in class StyleConverter<String,E extends Enum<E>>

Parameters:

value - The ParsedValue to convert

not_used - The Font to use when converting a relative value.

Returns:

the converted target property type

writeBinary

public void writeBinary(DataOutputStream os,
                        StyleConverter.StringStore sstore)
                 throws IOException

Description copied from class: StyleConverter

Write binary data.

Overrides:

writeBinary in class StyleConverter<String,E extends Enum<E>>

Parameters:

os - the data output stream

sstore - the string store

Throws:

IOException - the exception

readBinary

public static StyleConverter<?,?> readBinary(DataInputStream is,
                                             String[] strings)
                                      throws IOException

Throws:

IOException

getInstance

public static StyleConverter<?,?> getInstance(String ename)

equals

public boolean equals(Object other)

Description copied from class: Object

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.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Overrides:

equals in class Object

Parameters:

other - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

Object.hashCode(), HashMap

hashCode

public int hashCode()

Description copied from class: Object

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by 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(Object) 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 Object.equals(java.lang.Object) 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.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (The hashCode may or may not be implemented as some function of an object's memory address at some point in time.)

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

public String toString()

Description copied from class: Object

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.
