Constructor Detail

AddressKeyIterator

public AddressKeyIterator(Table table,
                          AddressMap addrMap,
                          boolean before)
                   throws java.io.IOException

Constructs new AddressKeyIterator that iterates over all addresses. Memory addresses encoded as Absolute are not included.

Parameters:

table - the database table key by addresses

addrMap - the address map

before - positions the iterator before the min value,otherwise after the max value.

Throws:

java.io.IOException - if a database error occurs.

AddressKeyIterator

public AddressKeyIterator(Table table,
                          AddressMap addrMap,
                          Address startAddr,
                          boolean before)
                   throws java.io.IOException

Constructs new AddressKeyIterator that iterates overal all addresses and is initially positioned at startAddr. Memory addresses encoded as Absolute are not included.

Parameters:

table - the database table key by addresses

addrMap - the address map

startAddr - the address at which to position the iterator.

before - positions the iterator before the start address,otherwise after the start address. If the start address is null, then before positions the iterator before the lowest address, !before positions the iterater after the largest address.

Throws:

java.io.IOException - if a database error occurs.

AddressKeyIterator

public AddressKeyIterator(Table table,
                          AddressMap addrMap,
                          Address minAddr,
                          Address maxAddr,
                          Address startAddr,
                          boolean before)
                   throws java.io.IOException

Constructs new AddressKeyIterator that iterates over an address range. Memory addresses encoded as Absolute are not included.

Parameters:

table - the database table key by addresses

addrMap - the address map

minAddr - the first address in the range.

maxAddr - the last address in the range.

startAddr - the address at which to position the iterator, can be null. The exact position of the iterator depends on the before parameter.

before - positions the iterator before the start address,otherwise after the start address. If the start address is null, then before positions the iterator before the lowest address, !before positions the iterater after the largest address.

Throws:

java.io.IOException - if a database error occurs.

AddressKeyIterator

public AddressKeyIterator(Table table,
                          AddressMap addrMap,
                          AddressSetView set,
                          Address startAddr,
                          boolean before)
                   throws java.io.IOException

Constructs new AddressKeyIterator to iterate over an address set. Memory addresses encoded as Absolute are not included.

Parameters:

table - the database table key by addresses

addrMap - the address map

set - the address set to iterator over (may be null for all defined memory)

startAddr - the address at which to position the iterator, can be null. The exact position of the iterator depends on the before parameter.

before - positions the iterator before the start address,otherwise after the start address. If the start address is null, then before positions the iterator before the lowest address, !before positions the iterater after the largest address.

Throws:

java.io.IOException - if a database error occurs.
