Class StringOps::StringOps::Concatenation

A data flow node that performs a string concatenation and returns the result.

Examples:

x + y
x += y
[x, y].join('')
Array(x, y).join('')
`Hello ${message}`

See ConcatenationNode for more information.

from Node
getFile

Gets the file this data flow node comes from.

from Node
getFirstLeaf

Gets the first leaf in this concatenation tree.

from ConcatenationNode
getFirstOperand

Gets the first operand of this string concatenation.

from ConcatenationNode
getImmediatePredecessor

Gets the immediate predecessor of this node, if any.

from ConcatenationNode
getNumOperand

Gets the number of operands of this string concatenation.

from ConcatenationNode
getOperand
