Method Detail

newInstance

public static FXGVersion newInstance(double version)
                              throws FXGVersion.FXGVersionException

Returns a FXGVersion object representing 'version' or null if 'version' is not a properly formatted version string. This routine is intended to be called internally and is suitable for use with version strings extracted from FXG files.

Parameters:

version - - the version double value.

Throws:

FXGVersion.FXGVersionException - if the version is invalid.

asString

public String asString()

Returns the version represented by this FXGVersion instance as a String value (e.g., "1.0", "1.2", etc.).

Returns:

String

equalTo

public boolean equalTo(FXGVersion version)

Compares whether this FXGVersion's value is equal to the value of the version parameter.

Parameters:

version - The version of FXG.

Returns:

true if this object's value is equal to the 'version' object's value; false otherwise

equals

public boolean equals(Object object)

Compares whether this FXGVersion's value is equal to the version value of the object. If object is not a FXGVersion, then false is returned. This method exists to provide compatibility with the common usage case of using equals(obj) to test object instance equality. It's use is discouraged because it is not a strongly typed method. The method equalTo(FXGVersion) is the preferred method to use for equality testing.

Overrides:

equals in class Object

Parameters:

object - The object.

Returns:

true if this object's value is equal to the 'version' object's value; false otherwise

hashCode

public int hashCode()

Returns the hashCode

Overrides:

hashCode in class Object

greaterThan

public boolean greaterThan(FXGVersion version)

Compares whether this FXGVersion's value is greater than the value of the version parameter.

Parameters:

version - A version of FXG.

Returns:

true if this object's value is greater than the 'version' object's value; false otherwise

asDouble

public double asDouble()

Returns:

the version double value.

getMajorVersion

public long getMajorVersion()

Returns:
