Class UserSymbolRecord.Value

java.lang.Object
  org.opensolaris.os.dtrace.UserSymbolRecord.Value

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<UserSymbolRecord.Value>

Enclosing class:

UserSymbolRecord

public static final class UserSymbolRecord.Value
extends java.lang.Object
implements java.io.Serializable, java.lang.Comparable<UserSymbolRecord.Value>

The composite value of a symbol's process ID and user address.

Immutable. Supports persistence using XMLEncoder.

Serialized Form

UserSymbolRecord.Value

public UserSymbolRecord.Value(int pid,
                              long addressValue)

Creates a composite value with the given user process ID and symbol address.

Supports XML persistence.

Parameters:

pid - non-negative process ID

addressValue - symbol address

Throws:

java.lang.IllegalArgumentException - if the given process ID is negative

getProcessID

public int getProcessID()

Gets the process ID associated with this value's user address.

Returns:

non-negative pid

getAddress

public long getAddress()

Gets the symbol's user address.

Returns:

the symbol's user address

equals

public boolean equals(java.lang.Object o)

Compares the specified object with this UserSymbolRecord.Value for equality. Returns true if and only if the specified object is also a UserSymbolRecord.Value and both values have the same process ID and the same address.

Overrides:

equals in class java.lang.Object

Returns:

true if and only if the specified object is also a UserSymbolRecord.Value and both values have the same process ID and the same address

hashCode

public int hashCode()

Overridden to ensure that equal instances have equal hash codes.

Overrides:

hashCode in class java.lang.Object

compareTo

public int compareTo(UserSymbolRecord.Value v)

Compares this value with the given UserSymbolRecord.Value and orders by process ID first and address second. The comparison treats addresses as unsigned values so the ordering is consistent with that defined in the native DTrace library. The compareTo() method is compatible with equals().

Specified by:

compareTo in interface java.lang.Comparable<UserSymbolRecord.Value>

Returns:

-1, 0, or 1 as this value's combined process ID and address is less than, equal to, or greater than the given value's combined process ID and address

toString

public java.lang.String toString()

Gets a string representation of this UserSymbolRecord.Value instance useful for logging and not intended for display. The exact details of the representation are unspecified and subject to change, but the following format may be regarded as typical:

 class-name[property1 = value1, property2 = value2]
 

Overrides:

toString in class java.lang.Object
