equals back to summary

equals	back to summary
public boolean equals(Object obj) 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. 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.

public boolean equals(Object obj)

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.

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.

getContext	back to summary
public ThreadContext getContext() throws IllegalThreadStateException Implements sun.jvm.hotspot.debugger.ThreadProxy.getContext. Doc from sun.jvm.hotspot.debugger.ThreadProxy.getContext. Retrieves the context for the given thread. It is only valid to call this method if the thread is suspended (i.e., the process has not been resumed via ProcessControl); throws an IllegalThreadStateException if it is not.

getContext

public ThreadContext getContext() throws IllegalThreadStateException

Implements sun.jvm.hotspot.debugger.ThreadProxy.getContext.

Doc from sun.jvm.hotspot.debugger.ThreadProxy.getContext.

Retrieves the context for the given thread. It is only valid to call this method if the thread is suspended (i.e., the process has not been resumed via ProcessControl); throws an IllegalThreadStateException if it is not.

public long getUniqueThreadId() this is not interface function, used in core file to get unique thread id on Macosx

hashCode back to summary

hashCode	back to summary
public int hashCode() 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. Returns:int a hash code value for this object

public int 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.

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.

Returns:int: a hash code value for this object

setContext	back to summary
public void setContext(ThreadContext context) throws IllegalThreadStateException, DebuggerException Implements sun.jvm.hotspot.debugger.ThreadProxy.setContext. Doc from sun.jvm.hotspot.debugger.ThreadProxy.setContext. Sets the context for the given thread. The passed ThreadContext must be a modified version of one returned from a previous call to getContext(). It is only valid to call this method if the thread is suspended (i.e., the process has not been resumed via ProcessControl); throws an IllegalThreadStateException if it is not. Throws a DebuggerException if the target process can not be modified, for example because it is a core file.

setContext

public void setContext(ThreadContext context) throws IllegalThreadStateException, DebuggerException

Implements sun.jvm.hotspot.debugger.ThreadProxy.setContext.

Doc from sun.jvm.hotspot.debugger.ThreadProxy.setContext.

Sets the context for the given thread. The passed ThreadContext must be a modified version of one returned from a previous call to getContext(). It is only valid to call this method if the thread is suspended (i.e., the process has not been resumed via ProcessControl); throws an IllegalThreadStateException if it is not. Throws a DebuggerException if the target process can not be modified, for example because it is a core file.
