@Override

Overrides org.graalvm.polyglot.impl.UnnamedToModuleBridge.UnnamedToModuleFileSystem.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.

Parameters

obj_:Object

the reference object with which to compare.

Returns:boolean

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

Returns a MIME type for given path. An optional operation for filesystem implementations which can provide MIME types in an efficient way.

Overrides default org.graalvm.polyglot.io.FileSystem.getTempDirectory.

Doc from org.graalvm.polyglot.io.FileSystem.getTempDirectory.

Returns the default temporary directory.

Annotations

@Override

Overrides org.graalvm.polyglot.impl.UnnamedToModuleBridge.UnnamedToModuleFileSystem.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.

Returns:int

a hash code value for this object

Annotations

@Override

Overrides default org.graalvm.polyglot.io.FileSystem.isSameFile.

Doc from org.graalvm.polyglot.io.FileSystem.isSameFile.

Tests if the given paths refer to the same physical file. The default implementation firstly converts the paths into absolute paths. If the absolute paths are equal it returns true without checking if the file exists. Otherwise, this method converts the paths into canonical representations and tests the canonical paths for equality. The FileSystem may re-implement the method with a more efficient test. When re-implemented the method must have the same security privileges as the toAbsolutePath and toRealPath.

Parameters

path1_:Path

the path to the file

path2_:Path

the other path

options_:LinkOption[]

the options determining how the symbolic links should be handled

Returns:boolean

true if the given paths refer to the same physical file
