PredicateHelper

A helper contract for executing boolean functions on arbitrary target call results

Functions​

or​

function or(
  address[] targets,
  bytes[] data
) external returns (bool)

Calls every target with corresponding data

Parameters:​

Name	Type	Description
targets	address[]
data	bytes[]

Return Values:​

Name	Type	Description
Result	bool	True if call to any target returned True. Otherwise, false

and​

function and(
  address[] targets,
  bytes[] data
) external returns (bool)

Calls every target with corresponding data

Parameters:​

Name	Type	Description
targets	address[]
data	bytes[]

Return Values:​

Name	Type	Description
Result	bool	True if calls to all targets returned True. Otherwise, false

eq​

function eq(
  uint256 value,
  address target,
  bytes data
) external returns (bool)

Calls target with specified data and tests if it's equal to the value

Parameters:​

Name	Type	Description
value	uint256	Value to test
target	address
data	bytes

Return Values:​

Name	Type	Description
Result	bool	True if call to target returns the same value as value. Otherwise, false

lt​

function lt(
  uint256 value,
  address target,
  bytes data
) external returns (bool)

Calls target with specified data and tests if it's lower than value

Parameters:​

Name	Type	Description
value	uint256	Value to test
target	address
data	bytes

Return Values:​

Name	Type	Description
Result	bool	True if call to target returns value which is lower than value. Otherwise, false

gt​

function gt(
  uint256 value,
  address target,
  bytes data
) external returns (bool)

Calls target with specified data and tests if it's bigger than value

Parameters:​

Name	Type	Description
value	uint256	Value to test
target	address
data	bytes

Return Values:​

Name	Type	Description
Result	bool	True if call to target returns value which is bigger than value. Otherwise, false

timestampBelow​

function timestampBelow(
  uint256 time
) external returns (bool)

Checks passed time against block timestamp

Parameters:​

Name	Type	Description
time	uint256

Return Values:​

Name	Type	Description
Result	bool	True if current block timestamp is lower than time. Otherwise, false
