Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`FlowModifier`	`and(FlowModifier that)`	Returns the `FlowModifier` with all modifications applied in `this` and `that` applied, with enable instructions taking precedence over conflicting disable instructions.
`<T> Output<T>`	`debug(Output<T> output)`	Writes a developer readable, debug-formatted string representation of this object to `output`.
`boolean`	`isReadDisabled()`	Returns `true` if the read operation should be disabled.
`boolean`	`isReadEnabled()`	Returns `true` if the read operation should be enabled.
`boolean`	`isWriteDisabled()`	Returns `true` if the write operation should be disabled.
`boolean`	`isWriteEnabled()`	Returns `true` if the write operation should be enabled.
`FlowModifier`	`not()`	Returns the `FlowModifier` with all applied modifications in `this` unapplied, and all unapplied operations in `this` applied, with enable instructions taking precedence over conflicting disable instructions.
`FlowModifier`	`or(FlowModifier that)`	Returns the `FlowModifier` with all modifications applied in `this` or `that` applied, with enable instructions taking precedence over conflicting disable instructions.
`static FlowModifier`	`valueOf(String name)`	Returns the enum constant of this type with the specified name.
`static FlowModifier[]`	`values()`	Returns an array containing the constants of this enum type, in the order they are declared.
`FlowModifier`	`xor(FlowModifier that)`	Returns the `FlowModifier` with all modifications applied in `this` or `that`—but not both—applied, with enable instructions taking precedence over conflicting disable instructions.

    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static FlowModifier valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - isReadDisabled
```
public boolean isReadDisabled()
```
    Returns true if the read operation should be disabled.

public boolean isWriteDisabled()
```
    Returns true if the write operation should be disabled.
  - isReadEnabled
```
public boolean isReadEnabled()
```
    Returns true if the read operation should be enabled.
  - isWriteEnabled
```
public boolean isWriteEnabled()
```
    Returns true if the write operation should be enabled.
  - or
```
public FlowModifier or(FlowModifier that)
```
    Returns the FlowModifier with all modifications applied in this or that applied, with enable instructions taking precedence over conflicting disable instructions.
  - xor
```
public FlowModifier xor(FlowModifier that)
```
    Returns the FlowModifier with all modifications applied in this or that—but not both—applied, with enable instructions taking precedence over conflicting disable instructions.
  - and
```
public FlowModifier and(FlowModifier that)
```
    Returns the FlowModifier with all modifications applied in this and that applied, with enable instructions taking precedence over conflicting disable instructions.
  - not
```
public FlowModifier not()
```
    Returns the FlowModifier with all applied modifications in this unapplied, and all unapplied operations in this applied, with enable instructions taking precedence over conflicting disable instructions.
  - debug
```
public <T> Output<T> debug(Output<T> output)
```
    Description copied from interface: Debug
    
    Writes a developer readable, debug-formatted string representation of this object to output.
    
    Specified by:
    
    debug in interface Debug
