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
