Address (jnr-ffi 2.2.4 API)

java.lang.Object
- java.lang.Number
- - jnr.ffi.Address

所有已实现的接口:

Serializable, Comparable<Address>
```
public final class Address
extends Number
implements Comparable<Address>
```
The Address class wraps a native address in an object. Both 32 bit and 64 bit native address values are wrapped in a singular Address type.
This class extends Number and implements all Number methods for converting to primitive integer types.
An Address instance is lighter weight than most Pointer instances, and may be used when a native address needs to be stored in java, but no other operations (such as reading/writing values) need be performed on the native memory. For most cases, a Pointer offers more flexibility and should be preferred instead.

  - Address
```
public Address(Address address)
```
    Creates a new address representation.
    
    参数:
    
    address - the native address.
- 方法详细资料
  - address
```
public final long address()
```
    Gets the native memory address represented by this Address as a long integer.
    
    返回:
    
    the native memory address
  - intValue
```
public final int intValue()
```
    Returns the value of this Address as an int. On 64bit systems, this will result in the upper 32bits of the address being truncated.
    
    指定者:
    
    intValue 在类中 Number
    
    返回:
    
    the numeric value of this Address after conversion to an int.
  - longValue
```
public final long longValue()
```
    Returns the value of this Address as a long.
    
    指定者:
    
    longValue 在类中 Number
    
    返回:
    
    the numeric value of this Address after conversion to a long.
  - floatValue
```
public final float floatValue()
```
    Returns the value of this Address as a float. This method is not particularly useful, and is here to fulfill the Number interface contract.
    
    指定者:
    
    floatValue 在类中 Number
    
    返回:
    
    the numeric value of this Address after conversion to a float.
  - doubleValue
```
public final double doubleValue()
```
    Returns the value of this Address as a double. This method is not particularly useful, and is here to fulfill the Number interface contract.
    
    指定者:
    
    doubleValue 在类中 Number
    
    返回:
    
    the numeric value of this Address after conversion to a double.
  - nativeAddress
```
public final long nativeAddress()
```
    Returns the native value of this address.
    
    返回:
    
    an long value representing the native value of this address.
  - hashCode
```
public final int hashCode()
```
    Returns a hash code for this Address.
    
    覆盖:
    
    hashCode 在类中 Object
    
    返回:
    
    a hash code for this Address.
  - equals
```
public final boolean equals(Object obj)
```
    Compares this address to another address.
    
    覆盖:
    
    equals 在类中 Object
    
    参数:
    
    obj - the other address to compare to.
    
    返回:
    
    true if this Address is equal to the other address, else false.
  - toString
```
public final String toString()
```
    Returns a String object representing this Address as a decimal value.
    
    覆盖:
    
    toString 在类中 Object
    
    返回:
    
    a string representation of this Address.
  - toHexString
```
public final String toHexString()
```
    Returns a String object representing this Address as a hex value.
    
    返回:
    
    a string representation of this Address.
  - compareTo
```
public final int compareTo(Address other)
```
    Compares two Address instances numerically.
    
    指定者:
    
    compareTo 在接口中 Comparable<Address>
    
    参数:
    
    other - the other Address to compare to.
    
    返回:
    
    0 if other is equal to this instance, -1 if this instance is numerically less than other or 1 if this instance is numerically greater than other.
  - isNull
```
public final boolean isNull()
```
    Tests if this Address is equivalent to C NULL
    
    返回:
    
    true if the address is 0
  - valueOf
```
public static Address valueOf(long address)
```
    Returns a Address instance representing the specified long value.
    
    参数:
    
    address - a long value
    
    返回:
    
    an Address instance representing address
  - valueOf
```
public static Address valueOf(int address)
```
    Returns a Address instance representing the specified int value.
    
    参数:
    
    address - an int value
    
    返回:
    
    an Address instance representing address
