Class DependencyKind

A library describing an abstract mechanism for representing dependency categories.

Import path

import semmle.python.dependencies.DependencyKind

Direct supertypes

Known direct subtypes

Predicates

isADependency

Identify dependencies associated with this category.

The source element is the source of the dependency.

Inherited predicates

charAt

Returns a one-character string containing the character in the receiver at the given index (which ranges from 0 through length minus one)

from string
indexOf

Returns all the offsets (starting at 0) at which the given string occurs in the receiver. Has no result if the string does not occur in the receiver.

from string
indexOf

Returns the index of the n’th (starting at 0) occurrence of the given string within the receiver, starting at the given 0-based offset. Has no result if the string does not occur in the receiver.

from string
isLowercase

Holds when the receiver contains no upper-case letters. This includes the case where the receiver contains no letters at all, for example, if it’s an empty string or only consists of non-letter symbols.

from string
isUppercase

Holds when the receiver contains no lower-case letters. This includes the case where the receiver contains no letters at all, for example, if it’s an empty string or only consists of non-letter symbols.

from string
length

Returns the length of the receiver (in UTF-16 code units)

from string
matches

Holds when the receiver matches the pattern. Patterns are matched by case sensitive string matching, and there are two wildcards: _ matches a single character, and % matches any sequence of characters. To match the actual characters _ or % in the pattern, they must be escaped using backslashes. For example, "anythingstring%".matches("%string\\%") holds. To match a literal backslash in front of _ or %, you must escape the backslash. In other cases, you don’t need to escape the backslash.

from string
prefix

Returns the substring of the receiver ending at the given 0-based exclusive offset

from string
regexpCapture

When the given regular expression matches the entire receiver, returns the substring matched by the given capture group (starting at 1). The regex format used is Java’s Pattern.

from string
regexpFind

Returns a substring of the receiver which matches the given regular expression. Also returns the offset within the receiver (starting at 0) at which the match occurred (occurrenceOffset), and the number of matches which occur at smaller offsets (occurrenceIndex). The regex format used is Java’s Pattern.

from string
regexpMatch

Holds when the given regular expression matches the entire receiver. The regex format used is Java’s Pattern.

from string
regexpReplaceAll

Returns a copy of the receiver with every substring which matches the given regular expression is replaced by the replacement. The regex format used is Java’s Pattern. The replacement string can contain references to captured groups as described in Java’s appendReplacement docs.

from string
replaceAll

Returns a copy of the receiver with all occurrences of the target replaced by the replacement

from string
splitAt

Returns all the substrings obtained by splitting the receiver at every occurrence of the argument. Trailing empty substrings are omitted. Splitting at an empty string returns all the characters that the receiver consists of.

from string
splitAt

Returns the n’th (starting at 0) substring obtained by splitting the receiver at every occurrence of the argument. Trailing empty substrings are omitted. Splitting at an empty string returns all the characters that the receiver consists of.

from string
substring

Returns the substring of the receiver which starts and ends at the given indices. Both indices are 0-based. The start index is inclusive and the end index is exclusive.

from string
suffix

Returns the substring of the receiver starting at the given 0-based inclusive offset

from string
toDate

Returns the date, if any, obtained by parsing the receiver. The recognized formats are described in the documentation.

from string
toFloat

Returns the 64-bit floating point number, if any, obtained by parsing the receiver. The parsing rules are described in Java’s valueOf docs.

from string
toInt

Returns the 32-bit signed integer, if any, obtained by parsing the receiver. The number may consist of an optional leading + or -, followed by one or more digits. Has no result if the value exceeds the value range supported by the int type.

from string
toLowerCase

Returns a copy of the receiver with all uppercase characters replaced by lowercase ones according to Unicode case conversion rules.

from string
toString

Returns the receiver

from string
toUpperCase

Returns a copy of the receiver with all lowercase characters replaced by uppercase ones according to Unicode case conversion rules.

from string
trim

Returns a copy of the receiver with all whitespace removed from the beginning and end of the string (where whitespace is defined as Unicode code points ‘\u0000’ through ‘\u0020’ inclusive)
