Method Summary

All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method and Description
`boolean`	`equals(java.lang.Object o)` Two divisions are equal if they: - they match type/version (ipv4, ipv6, mac, or a specific division class) - match bit counts - match values Prefix lengths, for those divisions that have them, are ignored.
`java.math.BigInteger`	`getCount()` The count of possible distinct values for this AddressComponent.
`int`	`getDigitCount(int radix)` Returns the count of digits of the value, or if a range, the larger value in the range
`long`	`getDivisionPrefixCount(int divisionPrefixLength)`
`abstract long`	`getDivisionValue()`
`long`	`getDivisionValueCount()`
`int`	`getMaxDigitCount(int radix)` Returns the count of digits of the largest possible value
`long`	`getMaxValue()`
`int`	`getMinPrefixLengthForBlock()` Returns the smallest prefix length possible such that this item includes the block of all values for that prefix length.
`java.math.BigInteger`	`getPrefixCount(int divisionPrefixLength)` The count of the number of distinct values within the prefix part of the address item, the bits that appear within the prefix length.
`java.lang.Integer`	`getPrefixLengthForSingleBlock()` Returns a prefix length for which the range of this item matches the block of all values for that prefix length.
`abstract long`	`getUpperDivisionValue()`
`java.math.BigInteger`	`getUpperValue()`
`java.math.BigInteger`	`getValue()`
`int`	`hashCode()`
`boolean`	`hasUppercaseVariations(int radix, boolean lowerOnly)`
`boolean`	`includesMax()`
`boolean`	`includesZero()`
`boolean`	`isBoundedBy(int value)` Returns true if the possible values of this division fall below the given value.
`boolean`	`isMax()`
`boolean`	`isMultiple()` Whether this represents multiple potential values (eg a prefixed address or a segment representing a range of values)
`boolean`	`isZero()`
`boolean`	`matches(long value)`
`boolean`	`matchesWithMask(long value, long mask)`
`boolean`	`matchesWithMask(long lowerValue, long upperValue, long mask)` returns whether masking with the given mask results in a valid contiguous range for this segment, and if it does, if it matches the range obtained when masking the given values with the same mask.

- Method Detail
  - isMultiple
```
public boolean isMultiple()
```
    Description copied from interface: AddressItem
    
    Whether this represents multiple potential values (eg a prefixed address or a segment representing a range of values)
    
    Returns:
    
    whether this segment represents multiple values
  - getMinPrefixLengthForBlock
```
public int getMinPrefixLengthForBlock()
```
    Description copied from interface: AddressItem
    
    Returns the smallest prefix length possible such that this item includes the block of all values for that prefix length.
    If the entire range can be dictated this way, then this method returns the same value as AddressItem.getPrefixLengthForSingleBlock(). Otherwise, this method will return the minimal possible prefix that can be paired with this address, while AddressItem.getPrefixLengthForSingleBlock() will return null.
    In cases where the final bit is constant so there is no such block, this returns the bit count.
    
    Returns:
    
    the prefix length
  - getPrefixLengthForSingleBlock
```
public java.lang.Integer getPrefixLengthForSingleBlock()
```
    Description copied from interface: AddressItem
    
    Returns a prefix length for which the range of this item matches the block of all values for that prefix length.
    If the range can be dictated this way, then this method returns the same value as AddressItem.getMinPrefixLengthForBlock().
    If no such prefix length exists, returns null.
    If this item represents a single value, this returns the bit count.
    
    Returns:
    
    the prefix length or null
  - getMaxValue
```
public long getMaxValue()
```
  - isZero
```
public boolean isZero()
```
    Returns:
    
    whether this item matches the value of zero
  - includesZero
```
public boolean includesZero()
```
    Returns:
    
    whether this item includes the value of zero within its range
  - isMax
```
public boolean isMax()
```
    Returns:
    
    whether this item matches the maximum possible value
  - includesMax
```
public boolean includesMax()
```
    Returns:
    
    whether this item includes the maximum possible value within its range
  - getDivisionValue
```
public abstract long getDivisionValue()
```
  - getUpperDivisionValue
```
public abstract long getUpperDivisionValue()
```
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class AddressDivisionBase
  - getValue
```
public java.math.BigInteger getValue()
```
    Returns:
    
    the value of the lowest item represented by this address item
  - getUpperValue
```
public java.math.BigInteger getUpperValue()
```
    Returns:
    
    the value of the highest item represented by this address item
  - getDivisionValueCount
```
public long getDivisionValueCount()
```
  - getPrefixCount
```
public java.math.BigInteger getPrefixCount(int divisionPrefixLength)
```
    Description copied from interface: AddressItem
    
    The count of the number of distinct values within the prefix part of the address item, the bits that appear within the prefix length.
    
    Returns:
  - getDivisionPrefixCount
```
public long getDivisionPrefixCount(int divisionPrefixLength)
```
  - getCount
```
public java.math.BigInteger getCount()
```
    Description copied from interface: AddressItem
    
    The count of possible distinct values for this AddressComponent. If not multiple, this is 1. For instance, if this is the ip address series subnet 0::/64, then the count is 2 to the power of 64. If this is a the segment 3-7, then the count is 5.
    
    Returns:
  - isBoundedBy
```
public boolean isBoundedBy(int value)
```
    Returns true if the possible values of this division fall below the given value.
  - matches
```
public boolean matches(long value)
```
  - matchesWithMask
```
public boolean matchesWithMask(long value,
                               long mask)
```
  - matchesWithMask
```
public boolean matchesWithMask(long lowerValue,
                               long upperValue,
                               long mask)
```
    returns whether masking with the given mask results in a valid contiguous range for this segment, and if it does, if it matches the range obtained when masking the given values with the same mask.
    
    Parameters:
    
    lowerValue -
    
    upperValue -
    
    mask -
    
    Returns:
  - equals
```
public boolean equals(java.lang.Object o)
```
    Description copied from class: AddressDivisionBase
    
    Two divisions are equal if they: - they match type/version (ipv4, ipv6, mac, or a specific division class) - match bit counts - match values Prefix lengths, for those divisions that have them, are ignored.

    equals in class AddressDivisionBase
  - hasUppercaseVariations
```
public boolean hasUppercaseVariations(int radix,
                                      boolean lowerOnly)
